STICKNEY, 0F HILLSIDE, NEW JERSEY, ASSIGNOR 'IO UNDERWOOD ELLIOTTFISHER COMPANY, OF NEW YORK LL- Y., A CORPORATION OF DELAWARE'IYIPEWRI'III'N'G- MACHINE Application filed May 13, 1925, Serial No.29,873. Renewed November 2'7, 1928.

This invention relates to machines for typing upon multiple-plyWork-webs, which may be either longitudinally folded or in the form ofloose plies interleaved with carbon-sheets, in which it is necessary toeffect shifting or stripping of the'carbons relatively to the plies ofwork-web'at the completion of the typing of each form, preparatory tosevering the web and typing the next form.

Usually a fixed length of carbon-paper is successively presented to newforms until worn out. After the typing of a form, it is usual first tolift the platen bodily to release the web therefrom and to release thecarbons for their shift; then to shift one form-length rearward, acarbon-carrier with the carbons attached thereto, while holding thework- Webs; and then to reset the composite web for commencement oftyping on the next form and to replace the platen.

It is an object of the invention to produce a simple, inexpensive andeasily operable machine of this kind, in which it is unnecessary todisplace the platen upwardly at the carbon-stripping operation.

The composite work-web is presented bot tom end first to the front ofthe platen, and is introduced downwardly and rearwardl under the'platen,the bottom form on the we being typed, then the next form above, and soon.

The bottom endof the web ma be initially introduced down around the outof the platen by the aid of the device shown in the Smith Patent No.1,402,804, of January 10,

' 1922; but thereafterthe web remains always in place around the platenuntil the web is used up, it being rendered unnecessary to disengage thewebfromthe platen for carbonstripping purposes, and it being furtherrendered unnecessary to provide a flexible backing or device forcarrying the composite web around the platen; the web being simply heldagainst the platen by feed-rolls of the usual type, which havesuiiicient power to carry out the backward and forward web feeding oradjusting operations hereinafter called for.

The carbon-sheets; which are placed or loaded between the work-webplies, are held at their upper ends by means of aset of blades,

which may be of the usualindividual construction, and the set of bladesmay form part of a carrier which is held stationary during thecarbon-stripping operation, that is, while the work-webs are pulleddownwardly by the act of revolving the platen backwardly; the rollsacting upon the lowermost form. At the initial introduction of the webinto the machine, this bottom form need not be t ed, but may be usedmerely as a tab, to ai in manipulating the composite web. The platen isthus revolved backwardly until the first line on the second form is inposition to be typed. During such backward rotation, both the work-websand the carbons feed backwardly around the platen. This composite webpulls down the carbon-carrier, which is mounted upon forwardly anddownwardly swinging arms. Adight returning spring upon thecarbon-carrier holds the web taut upon the platen.

The composite web having thus been introduced by using the bottommostform thereof as a tab for this purpose, and the web having then beenbrought to typin position by revolving the platen backwar ly, the firstform is typed; and during this operation the web is advanced line byline, by means of the usual line-spacing mechanism of the typewriter.This operation proceeds until the form is completely typed.

The next step is to effect the stripping of the carbons, and preparatoryto this step the platen is advanced a little, until the lower ends ofthe carbons are clear from the platen, so that they extend in a straightline from top to bottom; this straight condition being desirable foreasy stripping or relative shifting between the carbons and work-web.

Just before stripping the carbons, the carbon-carrier is locked againstmovement; and the stripping consists in drawing downwardly the web-pliesby the co-operation of the platen and the feed-rolls that run there on.For this purpose the platen is revolved backwardly to the extent of oneform; the operator being able to see the bottom edges ofthecarbons-through the outer web-form, and therefore to note atwhat pointto stop Then the operator unlocks the carbon-carrier, permitting it toswing, and also clamps the work-web to the carbon-carrier so that boththe work-web and the carbons will par- 5 take of further downwardmovement. This further movement of the composite web 1s effected by thecontinued backward rotation of the platen, which is not stopped untilthe next form of the web is in position to have the first line typedthereon.

Before the web reaches the position for typing the second form thereon,the form at the bottom of the web is severed. The first form to besevered in this way is untyped,

' as already explained. After the web-severup to its extreme position,and is there locked at which time the carbons and the web interleavedthereby are in straight condition, this being preparatory to the nextstripping operation.

which is severed is the one which was first typed; there alwaysremaining in the machine thereafter one typed form, which is used as aspare form for the pur ose of aiding in the manipulation of the we andcarbons in the manner stated.

The severing knife is mounted at the rear of the platen to sever thetyped web without necessitating the withdrawing of the web from theplaten.

Another feature relates to means for simultaneously locking thecarbon-holders and for releasing a clamping member normally holding theweb in registration with the carbons.

Other features and advantages will here- In the next cycle ofoperations, the form Still another feature relates to a novel elevation,showing the web-clamp in its efiective position.

Figure 5 is a diagrammatic side v1ew,-1n elevation, showing the work-webin cuttingoif position.

Figure 6 is 9, dia rammatic side view,..in elevation, showing t e knifein its operated position.

Figure 7 is a cross-sectional view, in eleva- ,tion, showing thework-web in its typing Then the web is interleaved with sheets of carbon14 and the leading edge of the web is inserted at the front of a platen15 which is backwardly rotated to feed the web to a position shown inFigure 1 by the co-operative'action of feed-rolls 16.

[he sheets of carbon are fastened to the movable table 12 by means ofindividual car-- bon-holding blades 17 and the table is held in aposition as shown in Figure 1 by means of a lock 18. The function ofsaid lock is to hold the table against displacement and to release aclamp 19 normally holding the work-web against the movable table orcarrier 12.

The lock 18 is then released and held in a position shown in Figure 4 bymeans of a holding spring 20 fast to the lock 18 and engaging with a pin21 fast to a supporting bracket 22,

upon which the lock 18 is pivotally mounted at 23. Having released thelock, the table or carrier 1s free to swing forwardly and the platen isrotated by means of a handle 24 fast to the platen-axle 25, tothusposition the work-sheet relatively to the printing point, in whichp'osition'the first line of typing is written upon the sheet byoperating type-bars 26. Upon releasing the lock 18, the clamp 19 isactuated by a spring 27 and the web is gripped against the table whichis pulled with the web as successive lines of typing. are written on theform. .The web 10 is held under tension at the delivery side of theplaten .by means of a spring 28 wound on a supporting shaft 29,'andacting against a pin 81 to swing the table 12 which 'is pivotallymounted at 30 upon supporting arms 31. As theusual line-spam ingmechanism (part of which is seen at Figure 8 in dotted linesin the formof a line-space wheel) .is operated to rotate the platen, the spring 28carries the web upwardly and rearwardly from the printing line on theplaten,

.' the operations of the web-lifter 28 and the carrier 12 being undercontrol of said line-spacing mechanism.

After the typing of the form, there is a stripping operation, by whichthe carbons are shifted to a new field of the web, that is to say,

. the carbons are held in a stationary position and the web is pulled tothus strip the carbons from the typed form and to present them to afresh form. To this end, the platen is rotated forwardly and the tableor carrier 12 is again held stationary by means of the lock 18, which isswung upwardly by means of a handle 32. Simultaneously with the lockingof the table against displacement, the clamp 19 is released to thus freethe work-web, as shown in Figure 1, whereupon the platen is cranked andthe web is pulled toward the platen while the carbons are heldstationary. Due to the translucent nature of the web-plies, it ispossible to distinguish a contrasting line determining the ends of thecarbon-sheets, and the contrasting line is made to register with a line33 on the printed form to thus position the new form relatively to theends of the carbonsheets. v

The lock 18 is again reached to render the clamp 19 effective to gripthe web and the platen is again cranked rearwardly to position the webfor cutting off the printed form. in order that the web may be severedat the rear of the platen, the machine is provided with a cylindricalknife 34 co-operating with a cutting edge 35 on a rear table 36. Saidrear table is an extension of the rear chute 37 of the machine, and isfastened to the platenframe by means of screws 38. The knife is providedwith a handle 39 and is pivotally mounted uponst'uds 40 and 41 journalediii support ng frames 42. In order to facilitate the cutting of the web,the knife is provided wlth a pitched cutting edge 43 to facilitateshearing the web. Another feature of the knife is its simple designwhich permits it to be made of a single sheet-metal piece bent to shapeand hardened at the cutting edge. At

the ends the knife is'provided with supportmg ears 44 carrying the studs40 and 41 fast thereto. The stud 40 rotates in a bushing 45 fast to theplate, and a portion of the stud protrudes to the outside of the bushingand carries the handle 39, secured thereon by means of a screw 46, thehandle being limited on its forward and rearward travel by means of pins80 fast to the supporting frames 42.

In order to readily locate the web around the platen in a position to besevered, there is provided a gage 47 controlled by the movement of thetable 12. Said mounted upon the shaft 29 and swings downwardly with thetable-supporting arms 31. However, the gage is not positively connectedto the arms, butis driven independently therefrom by the action of aspring 48, which tends to hold the head 49 of a stud 50 against one ofthe arms31. In thisma'nner, when the the arms 31 are swung forwardly,the gage will follow by the action of the spring, and when the arms areswung rearwardly, then gage is pivotally the gage will be positivelydriven in the same direction. Referring to Figure 5, in which the web isshown in cutting-oft position, it will be noted that theend 51 of thegage is provided with an indicating finger 52 which co-operates with afixed pointer 74 to indicate the cutting-off position relatively to thecarbon-holders Due to the resilient connection between the gage 47 andthe arm 31, it is possible to lower the table to the printing positionshown in Figure 7, and at the same time stop the swing of the gage whenstriking a surface 53, as shown in said Figure 7.

In order that'this device may be adapted to different form-length, thereare provided means for adjusting the position of the gage relatively tothe arms 31. Said means may comprise an arcuate slot 54 into which thestud 50 is slidably mounted and locked by means of a nut co-operatingwith a threaded end 56 of the stud 50. The stud is secured to the gagein a position corresponding to the length of the form, which length isindicated by figures 57 adjacent the slot In order to render theadjustable stud operable with one hand only, there is provided aprojectin g rib 58 fitting into the slot 54 and slidable therein. sothat in order to change the position of the stud, the nut is loosenedand the stud is moved in the slot Having severed the typed form, thenthe platen is again cranked forwardly to slacken the weband the lock isthrown to its effective position to release the clamp so that the webmay be pulled forwardly by the action of the platen and the feedrolls,to thus present a fresh form to the carbon-sheets. Then the form istyped and cut off, and the cycle of operations is repeated.

The web is led over the movable table or carrier 12 from the rear of themachine and is passed under a cross-rod 59 secured to cars 60 by meansof screws 61. The rod is provided with a groove 62 into which the pointof a screw 63 is slid to position the guides 13 to suit the width of theweb. Said table is also provided with upwardlyextending ears 64 uponwhich the shaft 65 is rotatably mounted. At the edge of the table thereare provided the carbon-blades 17 of usual design. said carbon-bladesbeing secured to the table by means of screws 66 and locating pins 67the blades being staggered to clear one another. as shown in Figure 8.

In order to facilitate the attaching of the device to an Underwoodstandard typewriter, all the mechanism is operatively mounted betweenthe two supporting frames 42, which 7 ing on the clamp 19, which isinturn backed by another pin 91 fast to one of the arms 31.

In order to prevent the sagging of the table when the tension on the'webis released, and in order to lock the table against displacement whenthe clamp 19 is released by the action of the lock 18, there is provideda pin 71 fast to one of the arms 31 against which the table strikes.

Advantage is taken of the device disclosed in the above-mentioned PatentNo. 1,402,80l, in which a plate 7 3 is fastened to the frame of themachine, said plate overlapping the edge 72, as shown in Figure 1, thusrendermg the introduction of the web an easy matter.

Owing to the design of the movable'table or carrier 12, and to theaction of the clamp 19 on the table, the latter is 'providedwith acounterweight 75 fast to the forward portion of the table. will be heldagainst the pin 71 even after releasing the clamp 19, which is actuatedby a pin 76 engaging a notch in a downwardlyextending finger 77 of saidclamp. For the purpose of increasing the gripping of the clamp upon thetable 12, there is provided a rubber tubing 78 over the clamping bar 79of the clamp.

The web is prevented from winding itself around the platen by means of aplate 82.

having an edge 83 close to the platen, so that the leading edge of theweb is confined between said plate 82 and the chute 37 and is led to theknife. Said plate 82 is secured to the table 36 by means of screws 84,and the plate is spaced from said table by means of spacing collars 85.

The work-web having a plurality of plies is drawn up from the supply atthe rear of the machine and is passed over a pivotally mounted tablebetween side gages. Then the plies are threaded between sheets of carbonwhich are held fast to the table by means of carbon-holding blades, andthe web is inserted at the delivery side of the platen. The platen isthen rotated by means of the handle 29 fast to its supporting axle, and,by means of the co-operating feed-rolls under the platen, the web is fedaround and is delivered at the normal introductory side of the platen.The arms on which the table is swingably mounted are then released andthe webis clamped to the table, so that both the carbons and the pliesof the web may be fed around the platen as a single pack. Again, thehandle on the platen is rotated rearwardly to impart to the platen aretrograde rotation, and

to present the first line of the form to the printing line, whereuponsubsequent linesof typing are printed on the form which is linefeed bythe regular line-space mechanism of the machine, and at the same timethe slack of the web at the delivery side of the platen In this mannerthe tableistaken up by a spring tending to rock the table away from theplaten.

After typing the first form, the platen is cranked forwardly to slackenthe web and lock 18 is operated to lock the table and to release theclamp, so as to free the web, whereupon the platen is rotated againrearwardly to strip the type form from the carbons and to present afresh form thereto. The-first form is presented 'to acuttingoff knife tobe severed by rotating the platen further rearwardly up'to a positionwhere a knife-gage having an indicating point corresponds with a fixedindicator on the platenframe. The knife is then operated to cut off theweb, and the typed form is delivered at the rear of the machine, thecycle of operations being repeated for each fresh form.

For the purpose of conducting the typed forms into a receptacle afterbeing cut off, there is provided an extension 86 of the table 36.Said'extensi'on is secured to the table at the ends thereof by means ofscrews 87, the front edge 88 of said extension being separated from thecutting edge 35 of the table 36 to clear the knife 3 L. The rear end ofthe extension is secured to downwardly-extending supporting pieces 89.bymeans of rivets ion means having, in combinatioma carrier overlying theplaten, and a plurality of carbonholding blades fast to the carrier.
